Sometimes I’ll follow simultaneous brainstorming with affinity mapping. To make an affinity map, take all the cards your group brainstormed and spread them out randomly on a table or virtual whiteboard. Then move the cards around so the ideas that are most similar are closest together, and the ideas that are least similar are farthest apart. Everybody works at the same time, moving cards as they see fit. In the end, the cards should end up forming clusters that you can name.
